Back to work since Jan 3rd.

subiquity

  • checked most bug reports opened during the Christmas break. Most of them are from users of the new subiquity-based desktop installer.
  • investigated LP: #2000066 - LVM edit crash with multiple disks. Wasn’t able to reproduce the crash but opened PR 1523 to add support for multiple disks in kvm-test.
  • Investigated LP: #1998920 - dns search domain gets duplicated. Turns out to be a known issue when submitting IP setitngs multiple times. It also affects DNS addresses. Needs fixing but we have to be careful not to break console_conf.
  • Fixed subiquity asynchronous command execution disregarding stdin when connected to a pipe PR 1524
  • Added confirmation dialogs in common subiquity code PR 1525
  • Focused on implementation of mirror testing for 23.04.
  • Got hit on multiple occasions with CI failures caused by GitHub API rate-limiting our queries. Created LP: #2001906 and will need to be addressed going forward.

autopkgtest

  • Removed End of Life releases from the autopkgtest databases on both web servers thereby freeing disk space on those units.
  • Submitted an MP to pass on a 404 traceback in the cleanup-instances tool.
  • Added lunar’s pyside2 to never-run for arm64 and s390x as it was continuously running in a loop.
  • Investigation into the looping test runs of dbconfig-common. It looks like a there is an issue connecting with postgres and the error message is ‘Temporary failure in name resolution’ which is considered an infrastructure issue and the tests are then running continuously. I submitted an an MP which should make the string considered a failure for the dbconfig-common package. I also cowboy’ed it into production.
  • Sent an email regarding updating autopkgtest in the Ubuntu archive.
  • Reported a bug regarding OK_PKG_STRINGS needing a rework.

Ubuntu

  • Submitted an MP to ubuntu-archive-tools modifying sru-release so it won’t comment on bugs if called with ‘–no-act’.
  • Sponsored a Lunar update of the autopkgtest Ubuntu package for @hellsworth.

Misc

  • Reviews of candidate essays.
  • Conducted an interview.

    Non-tech things are mostly done, still learning Ubuntu developing workflow and process.
